A great book for helping children develop an understanding of the fine line sometimes necessary to balance honesty and tact.  When Kim has a lesson on honesty at school, she declares a policy of always being honest, but she takes it too far, thinking it’s no longer okay to pretend to be a princess, but that it is okay to say everything she thinks, even when it’s hurtful to others.  Of course this causes problems with friends.  In the end, she discovers the trick of finding something to say that is both truthful and kind.
